The Plymouth Rock Breeders Thread- Part Deux

[nicalandia]

Drooling on the yellow. Big issue with my birds. Will be the heaviest cull this year. I intend to hatch many...

Is this about yellow shanks on Black Rocks?

Finally got some okay pictures of my male. Bearing in mind that he's still young and I've seen his tail higher when he's "up," I really like him. Note, he's not knock kneed either, he was taking a step, lol.

He's a good start for sure. I like him.

My cocks seem to have more fluff than tail. Frustrating. Your K has a tail coming in, happy for you and can't wait to see what your trio puts out over the season. Should get some nice breeders from that pen.

@nicalandia yes, the bright yellow legs. It's common for Plymouth of all varieties, excepting white, to have leg color issues.

I sat my first 10 today
One hen lays more porous shells than the other, the one I like less of the two.

Are you working with Black PR? If so pics of them would be nice, if Not creating a Black Line is kind of straight forward(breeding for yellow legs takes longer)

No I'm not working on Black. I've no intent to get more varieties than I can properly work on. I breed Silver and have a handle on what my flock can do, produce. It needs some work in areas that is faster to gain with another line than tease it out of what I have. The Partridge pullets I picked up needs work on legs and comb.

Starting in few weeks and for most of the year I'm hatching every egg from the F1 Silver cock over the two Partridge hens. Knock on wood they will niche well.

The mating of Silver over Partridge will make Silver pullets and S/G (yellow) K's. The Silver pullets speak for themselves- find breeders for Silver line. The prize of S/G k's will go back over the Partridge Dams to start the Partridge line. If the S/G breeder is all that and a bag of chips he'll also cover his Silver sisters to bring even more of the Partridge body type into the Silver line.

Thanks for posting what you are working on, but It's kind of hard to follow your breeding nomenclature.

K= Cockerels
S = Silver
G= Gold
S/G = Yellow.

Conventional nomenclature would be s+ for recessive sex linked gold, S for dominant sex linked silver. S/s+ golden, I have seen newer nomenclature forgetting about the + and / signs, perhaps I have become old fashioned? I for one like to put the + sign on the wild type allele to distinguish it from the mutant allele.

I would also point out that while breeding Silver partridge rooster over gold partridge hens will produce 100% Silver partridge hens, they will also inherit any autosomal red enhancers like autosomal gold/red, this will not be noticeable on your F1 females but if you use them on your silver partridge line they will produce golden like roosters(perhaps a shade lighter than true golden S/s+), have you made any Back cross to Silver partridge yet? Would be nice to see the BC1 roosters.

Yes they will have potential to be brassy- autosomal red. Knocking on wood they niche well and little is hidden under the Gold. I've retained three Murphy hens, that line carries no inclination to brass. True Silver expression. Will have to wait to see what is hiding under the Gold before nailing down the complete plan.

Layman's terms work just fine for what I'm doing. Sure I could be meticulous and write every gene out correctly but that only covers a small portion of everything going on.

Autosomal red, leg color, side sprigs are all areas of importance that express from multi gene loci combinations. We have no code to write. To write out precise the S/S, S/-, S/G. G/-, G/G is really not needed unless a need to explain it to someone.

K's is shorthand for cockerels. Very common usage in breeding and show. P for pullet, C for cock. Think that's being polite as I've never seen hen abbreviated.

What's quickly becoming a pet peeve of mine is the usage of "golden". I mean the bird is gold or not. There are varieties of other breeds called golden. These are decidedly G/G with inhibitor of some kind to deep color. They breed true and are golden. S/G does not breed true and in my mind not "golden". They be yella

Gold hides very little or nothing(is either enhanced or diluted and in the case of Self Buff birds is both enhanced and diluted), what you are looking for is what your Silvers are hiding!

Clean Silver lines according to Mr. Brian Reeder usually hide(at least the cleanest of the Silver Lines) a gold diluter either in recessive or dominant fashion, as it turns out it's easier to breed for brassy or yellow duckwing/partridge than is to produce a clean silver phenotype.
